Zokhudza Kuwala kwa UV

1. Choyamba, kodi mukumvetsa tanthauzo la kuwala kwa UV? Kodi kumagwira ntchito bwanji?

UV ndi chidule cha Ultraviolet Rays, kapena kuwala kwa ultraviolet, komwe kumakhala ndi mafunde a 100 mpaka 400 nm, komwe ndi mafunde a electromagnetic pakati pa X-ray ndi kuwala kooneka. Izi zikutanthauza kuti kuwala kumeneku ndi kuwala kwamphamvu komwe kumalowa ndikupereka kutentha m'thupi.

Kuwonongeka kwa kuwala kwa dzuwa pakhungu la munthu kumachokera makamaka ku ultraviolet A (UVA) ndi ultraviolet B (UVB). UVA ndi ya mafunde aatali, imagwira ntchito pakhungu lozama, ntchito yake imachepa, koma ingayambitse mdima kamodzi kokha. UVB ndi ya mafunde apakati, imagwira ntchito pamwamba pa khungu, zotsatira zake zimakhala zachangu. Ikhoza kuyambitsa ma keratinocyte a khungu, kotero kuti mitsempha yamagazi imakula, kuwonjezera kuyenda kwa magazi, chiyambi chake chidzakhala chofiira, kenako pang'onopang'ono chimakhala bulauni. Chifukwa chake, mwachidule, UVB imabweretsa "kufiira kwa dzuwa" ndipo UVA imabweretsa "kuda kwambiri kwa dzuwa".

Zotsatira: Kawirikawiri amagwiritsidwa ntchito ngati mankhwala pochiza misala yoyera, zomwe zikutanthauza kuti kudzera mu kuwala kwa ultraviolet kumeneku, kuyambitsa mwachindunji kwa banga loyera pansi pa khungu la tyrosine enzyme kumalimbikitsa kupanga melanin, khungu loyera kukhala lakuda.

Tingapeze zida zambiri zoyera zoyera zoyera zoyeretsera kuwala kwa UV pa intaneti, tikhoza kuyesa kusaka.

2. Kodi opanga ena amagwira ntchito yotani pogwiritsa ntchito kuwala kwa UV mu makina owunikira khungu?

Kaya kuwala kwa UV kukuvulaza khungu kapena ayi, mabizinesi ena pamsika amagwiritsa ntchito kuwala kwa UV pakhungu. Zinthuzi zimagwiritsidwa ntchito kwambiri poona mawanga ndi ma pores (pamwamba pa khungu). Zinthu ziwirizi ndizochepa kwambiri pa ntchito yozindikira, chifukwa chiyani? Mtundu wa khungu ungapezeke kudzera mu zathu. Makina Osanthula Khungu la Magalasi Amatsenga, angapezenso malowo, chifukwa chiyani ayenera kufunikira chida kuti azindikire, ngatiChipangizo Chowunikira KhunguTimaganiza kuti n'kofunika kwambiri kuona malo a mtundu pansi pa derm.
